Some people can go their entire lives without having to learn the true meaning of a tragedy, without ever having to experience the gut wrenching pain it causes. My family was not fortunate enough to be spared from the experience.
About a month ago, my dad started having knee pains. Working two jobs, he couldn't afford to take off to rest, and with no health insurance, he had no other option but to work through the pain. He took a couple of ibuprofen, and kept working. In a few days, dad's knee pain turned to stomach pain, so he took a few more ibuprofen. He started to get sick. He couldn't eat anything, and would throw up everything. But he kept working, because he had no other choice.
